Spinel is a good candidate for the title of \u201cHistory\u2019s Most Underappreciated Gems.\u201d Some Ancient mines that supplied gems for royal courts, from Rome to China, produced spinels. Yet, they were usually confused with better-known stones like ruby and sapphire.Spinels history dates back to the 1300’s, and it\u2019s a central stone in the British Imperial State Crown.<\/p>\n
Modern technology hasn\u2019t helped spinel\u2019s confused identity either. At least as far as the general public is concerned. This is largely due to the widespread use of synthetic spinel as an imitation for many other gems. Most customers don\u2019t even know there\u2019s a natural version of the stone. Limited availability also contributes to spinel\u2019s lack of public recognition. Gem-quality material is typically transparent and faceted, but it\u2019s hard to find in sizes larger than 5 cts.<\/p>\n
Spinel\u2019s color range includes violet, blue, orange, red, pink, and purple. Blue spinels are often grayish and subdued, but the best are a deep rich color. The reds can rival fine ruby. The vivid orange to orange-red stones merit their name\u2014flame spinel. Some spinels show color change, usually turning from grayish blue in daylight or fluorescent light, to purple under incandescent light. Spinel is a hard, tough stone that\u2019s suitable for daily wear in any type of jewelry.<\/p>\n
